IMPROVED WASHING-MACHINE.

Specification forming part of Letters Patent No. 55,610, dated June 19,1866.

To all whom it may concern:

Be itknown that I, H. BUCKNALL, of Darien, in the county of Walworth andState of Wiscousin, have invented a new and Improved Washing-Machine;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of' this specilication, in which.y

Figure lis a longitudinal vertical central section of my machine. Fig. 2is a detached view ot' the cam I employ for elevating the rubbing-board.

My invention consists in hanging the rubbing concave or bed in a grooveat one end of the machine, so that it will swing loosely in the tub;also, in the employment of a cam of peculiar construction for elevatingand lowering the rubbing concave or bed; also, in the employment of athumb-screw for regulating the length of the arm in which therubbingboard is suspended; also, in making a joint at the end oi saidrod, so as to enable the board to rise or lower at either side, toadjust itself to the thickness of the clothes being washed.

A. designates the box or tub, which may be ot' any suitable form orconstruction. B is the roller-concave, a a, being the rollers journaledtherein. This concaveis hung looselyin the box by pivots or journals,which are letinto grooves b in either side of the box, and thus it ispermitted to have a rising or falling motion. This concave, by reason ofthus hanging it, is enabled to be submerged so as to bring the clothes(whether there be a greater or less quantity) under or above the surfaceof the water, as may be desired.

C is the rubbing-board, which,in the present instance, is a luted boardsecured to arms D, connected at their ends by a rod, c, which may betaken hold of when operating the rubbingboard. E is a rod, which isjointed at its lower end to a cross-rod, d, connecting the two otherends of the arms D D. The joint designated by the letter e allows therubbing-board to have an up-and-down lateral play, so as to enable it toride freely over any inequalities in the thickness of the clothes ateither side of the machine. The other end of the rod is connected by athumbscrew, f, to a rock-shaft, F, which extends across from twouprights, Gr G, attached to each side of the machine. By operating thisthumb-screw the height of the rubbing-board may be regulated as desired.The uprights G G carry on their ends cams H, which are pivoted thereto,and these cams (refer to Fig. 2) have a quirl-shaped groove, h, cut intothem, which plays on a pin, q, and thus by turning the cams theuprights, and consequently the roller concave, may be elevated in thebox, as can be readily understood by reference tothe two iigures of thedrawing.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the rubbing-concave B, hung looselyin the machineby journals or pivots, with the uprights G, cam H, and rubbing-bar C,substantially as shown and described.

2. The cam H, in combination with the uprights G G and pin g, whenconstructed and operating substantially as and for the purposespecified.

3. The thumb-screwf, for raising and lowering the rubbing-board C, incombination with the rock-shaft F and rod E, as shown and described.

4. In a washing machine constructed substantially as described, theemployment of a joint, e, at the connection of the rod E and thecross-rod d, substantially as and for the purpose specified.
